Which of the following is NOT a typical consideration in the take-off calculation for piping?

In the context of take-off calculations for piping, the focus is primarily on those components that directly affect the quantity and sizing of the materials required for a piping system. Typical considerations include the fittings used, the length of the run, and the diameter of the pipe, as they all contribute to the total volume of materials needed for installation.

The fittings are critical in determining how much additional material will be needed to accommodate bends, elbows, tees, and junctions in the piping layout. The length of the run is essential for calculating the total linear footage of pipe required, and the diameter of the pipe affects the sizing and volume capacity of the system, influencing both material selection and pressure considerations.

In contrast, while the type of pipe support used is important in the overall design and installation of a piping system, it does not directly impact the take-off calculation of the piping materials themselves. Pipe supports relate more to the structural integrity and stability of the piping system rather than the direct material requirements needed for the actual piping run, making it a less relevant factor in the initial take-off calculations.
